Super dodgeball pcb problem

[Mkr1981]

I have an issue with a super dodgeball pcb i bought recently. The video is showing, but the volume is so low with a humming sound and there is no response when using my neogeo controller. Im using a supergun made by netropolis.

Any suggestion is highly appreciated.
Thanks,

Does this pcb need -5v? I'd check that first when it comes to sound.

How to know that?
Do i need a different power supply?

According to the manual you do need -5v for sound.

You need to look at your PSU and SG to make sure they are providing -5v. Post some pictures of both and we'll try to help.

From the eBay listing it doesn't provide -5v.

"This particular SuperGun's PSU can operate boards requiring +5 Volts DC @ 4 Amps and +12 Volts DC @ 1 Amp. If you'd like a unit with different power options, be sure to let us know as we can customize it to your needs!"

I'm not sure how to remedy that problem, maybe contact the seller/builder and ask for direction.

If you buy a different SG, I highly recommend one these forums recommend, such as the HAS (my favorite), the mini, the Axun, etc. That SG is not recommended by most people on these forums.

Not to mention that price. .ouch!

That’s insane, should be 100 USD tops, Kenny boy likes a profit.

Also, not to dogpile, but 4 amps for +5V is low. Something to keep in mind if you ever try to connect a power hungry board to it.

I was trying to not make the OP feel bad about his purchase!

Everyone needs to start somewhere, I just we could all start here for advice!

My advice for now is to get a negatron. Since it seems that you're new Google JAMMANATIONX or pm @XianXi who may be able to whip up a Jnx atlas with a negatron which will provide your -5v needed on some pcb especially Super Dodgeball.

I feel bad for approaching such hoppy like that.. Lesson learned.
I reached out to @XianXi for help.
Thank you all

The Supergun does look well made but it should have a -5V, that’s a rookie error by Kenny boy.
